Synthetic stacked visualization of 3,667 multivariate community comparisons from a global biodiversity meta-analysis. Blue points represent reference sites and red points impacted sites. The two clouds overlap, but impacted communities show a clear directional shift away from reference communities.

Our paper “The global human impact on biodiversity” turns one today! 🎂
This figure did not make it into the paper, but I still think it is the most striking. It stacks the 3667 multivariate analyses. Each point is a community. 🔵=reference; 🔴=human-impacted.

Les zones alluviales sous pression : les zones protégées actuelles sont insuffisantes Une étude du WSL montre que les espèces alluviales ne survivront qu’avec une planification adaptée.

Les #ZonesAlluviales sont riches en espèces et menacées. Face à l’évolution des conditions climatiques, les zones protégées ne suffiront plus. Une étude du WSL montre les mesures à prendre pour continuer à accueillir des espèces rares. www.wsl.ch/fr/news/les-...

Rocky, mostly dry riverbed in a forested mountain gorge with overlaid text asking how much hydroelectric potential is lost to residual flow requirements.

A research team from @wslresearch.bsky.social, #unibern and @eawag.bsky.social shows: The additional #reducedproduction due to residual water is likely to be significantly lower than feared from today in 2050. mediarelations.unibe.ch/media_releas...

Braided rivers look chaotic, but their food webs tell a different story.
Using stable isotopes, we found that fish, birds, and spiders connect resources across huge spatial scales — revealing hidden structures that help stabilise these dynamic ecosystems.

We've got ISSUES. Literally.

We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do?

Mitigating the effects of extreme low-flow on stream macroinvertebrates: the role of woody riparian vegetation and groundwater - Hydrobiologia We investigated the role of woody riparian vegetation (WRV) in reducing the detrimental effects of extreme low-flow conditions on macroinvertebrate communities in Central European streams. We hypothes...

We investigated how #riparian shading and #groundwater influx mitigate #lowflow and benthic invertebrates in lowland streams. The study highlights riparian management as a key tool for protecting stream ecosystems from droughts and related low-flow. link.springer.com/article/10.1...

How do #beaver activities modify #aquatic invertebrate communities? We published a first comprehensive quantification based on 188 habitat-specific invertebrate samples that yielded more than 82,000 individuals. One of our more important papers. onlinelibrary.wiley.com/doi/10.1111/...

Can semi-aquatic insects track the quality of terrestrial subsidy ? We found that predators responded the most, followed by shredders. Dispersal traits did not respond at all. In brief, predators and shredders are transmission belts of cross-ecosystem perturbations (see 🧵for more). 🧪💧🌎
